Abstract
The present invention relates to a kind of valve position feedback method, the valve connection supplementary speed reduction means is transmitted in computer display screen by the multipoint recording to retarding stage angle, and the angle opened with computer control valve compares, to obtain the position of valve.
Description
Technical field
The present invention relates to valve positioning, more particularly to a kind of valve position feedback method.
Background technique
Currently, the continuous improvement of the automatization level with Industry Control, has more and more equipment to need to flow
It closes or big minor adjustment carries out automatically controlling, this just needs to carry out the working condition of valve timely accurate understanding, ability
It is controlled.In the prior art, valve position situation generallys use the sensor letter that common simulation circuit carrys out Sampler valves locator
Number, and corresponding valve position current signal feedback is generated to Upper system.The precision as existing for analog circuit is low, stability
The defects of poor, so leading to this technology there is feedback accuracies and is lower.
Summary of the invention
For above-mentioned deficiency in the prior art, the present invention provides a kind of valve position feedback methods, and feedback accuracy is more
It is high.
In order to solve the above technical problems, technical solution provided by the invention are as follows: a kind of valve position feedback method, the valve
Door connection supplementary speed reduction means is transmitted in computer display screen by the multipoint recording to retarding stage angle, with computer control
The angle that valve processed is opened compares, to obtain the position of valve.
As improvement: the retarding stage includes gear one and gear two, and the big number of teeth of the gear two is greater than one number of teeth of gear,
The gear two is connect with valve.
As improvement: the method for obtaining retarding stage multiple spot angle information are as follows: be equipped with angle sensor in gear one and gear two
Device, and connect with computer, angular transducer zero degree position is set, valve open angle is given by computer, valve stops
When, the angle information of gear one and gear two is shown on computers.
As improvement: by the conversion between angle, calculating valve actual rotation angle, carried out with computer given angle
Compare, when identical, valve is then controlled a position, if when actually opened angle and computer given angle difference, if giving
Angle is determined greater than actual rotation angle, then actual open position is greater than the given angle of computer, if computer gives angle
Degree is less than actual rotation angle, then actual open position is less than the given angle of computer.At this point, being carried out by computer
Micro-adjustment, reach computer given angle with practice that rotational angle is identical, so that it is determined that the absolute position of valve.
As improvement: when computer given angle and actual angle difference, after calculating angle difference by computer,
Be micro-adjusted, reach computer given angle with practice that rotational angle is identical, so that it is determined that the absolute position of valve.
After using the above structure, the present invention has the advantage that carrying out the angle inspection to retarding stage using angular transducer
It surveys, is compared after calculating with given valve rotational angle, determines valve open position, simple and effective, feedback accuracy is higher, more
Add stabilization.
Detailed description of the invention
Fig. 1 is a kind of system schematic of valve position feedback method of the present invention.
Specific embodiment
Present invention will be described in further detail below with reference to the accompanying drawings.
In conjunction with attached drawing 1, the valve connection supplementary speed reduction means is transmitted to by the multipoint recording to retarding stage angle
In computer display screen, the angle opened with computer control valve compares, to obtain the position of valve.
The retarding stage includes gear one and gear two, and the big number of teeth of the gear two is greater than one number of teeth of gear, the gear
Two connect with valve.
The method for obtaining retarding stage multiple spot angle information are as follows: be equipped with angular transducer in gear one and gear two, and with meter
The connection of calculation machine, is arranged angular transducer zero degree position, gives valve open angle when valve stops by computer and is calculating
The angle information of gear one and gear two is shown on machine.
By the conversion between angle, valve actual rotation angle is calculated, is compared with computer given angle, it is identical
When, valve is then controlled a position, if when actually opened angle and computer given angle difference, if given angle is greater than
Actual rotation angle, then actual open position is greater than the given angle of computer, if computer given angle is less than reality
Rotational angle, then actual open position is less than the given angle of computer.At this point, being micro-adjusted by computer, reach
To computer given angle with practice that rotational angle is identical, so that it is determined that the absolute position of valve.
When computer given angle and actual angle difference, after calculating angle difference by computer, it is finely adjusted
It is whole, reach computer given angle with practice that rotational angle is identical, so that it is determined that the absolute position of valve.
The present invention and its embodiments have been described above, this description is no restricted, shown in the drawings
Only one of embodiments of the present invention, actual structure is not limited to this.All in all if the ordinary skill of this field
Personnel are enlightened by it, without departing from the spirit of the invention, are not inventively designed and the technical solution phase
As frame mode and embodiment, be within the scope of protection of the invention.
